Abstract

Cette invention se rapporte à des systèmes de communication et, plus particulièrement, à l'amélioration de la tolérance aux pannes dans des éléments de réseau et des systèmes de transmission. On obtient la tolérance aux pannes: (1) en prévoyant au moins deux connexions de canal virtuel permanent (PVC) ATM actif (31a-31d) entre un élément de réseau de noyau (3G-SGSN) et un élément de réseau d'accès (RNC), et (2) en prévoyant une unité d'interface ATM séparée (IU1-IU4) pour chacune de ces connexions PVC ATM dans l'élément de réseau de noyau (3G-SGSN). Le trafic d'utilisateur et de signalisation est distribué parmi ces connexions actives et ces unités d'interface. En cas de panne dans l'une des connexions PVC ATM ou dans l'une de ces unités d'interface (IU1-IU4), la communication est maintenue sur la ou les autres connexions et sur la ou les autres unités d'interface. Ainsi, une partie seulement de la capacité de transport est perdue et un blocage total des communications est évité. Toute nouvelle communication va être établie sur les autres connexions.
